This is the best backflow testing and certification we've experienced from start to finish in terms of cost and quality. We were able to schedule the work at a guaranteed time which was a first ever for a service call and was truly a day saver. Jack arrived even earlier but waited till the appointed time to ring the door bell. He was very professional, respectful, knowledgeable, efficient and a pleasure to work with. Besides Jack, all the staff we dealt with were wonderful. Being a family owned business, they treat their customers like family. We certainly highly recommend Chicago Backflow and will be using them for future plumbing needs!

Top notch service!!! We are a new to the area company that needed a portable RPZ to use on city of Chicago hydrants, the owner himself took the time to sit down with us and write down exactly what to get and where to get it. They also set up a prompt test date for it. Thanks again!

We used CBI for our backflow inspections. They were extremely responsive and quick to give us pricing. The technician, Mark, was on time, professional, quick, efficient and able to answer many question I had about our specific devices. Couldn't have asked for a better experience. CBI had much better pricing than other companies in the area who we've used in the past. 5/5.

Chicago Backflow was very professional from the office staff to the onsite technician. The office staff provided a time-window and Genaro, the technician called early and showed up on-time.As a plumbing novice, I do not have much experience with backflows or plumbing. I highly encourage to opt for their $150 test/repair package instead of the standard $99 for first-time customers. It is slightly extra but if the backflow test were to fail, you might be quoted the standard price that will be substantially more.
